The investigation into a large E. coli O157 outbreak linked to a UK petting zoo continues, and the number of potentially exposed people is astounding. There are a couple of reasons that I write a fair bit about petting zoos, and they are highlighted here: the potential for exposure of a large number of people and
Testing petting zoo animals
I received the following comment in response to a recent E. coli O157 and petting zoos post, and thought that it merited a post of its own.
"Why doesn’t the petting zoo owners have a fecal swab sample taken from each animal in the petting zoo and submitted for STx PCR screen testing. If
Verotoxigenic E. coli in petting zoo animals: UK
I’ve written several posts about petting zoos, mainly about the potential negative aspects, although I still think they’re valuable if run properly. A major concern with these events is exposure of people to zoonotic infectious diseases, particularly harmful bacteria that can be carried by healthy animals. One of the more common pathogens that causes disease
E. coli outbreak at a petting zoo
The latest edition of the CDC’s Morbidity and Mortality Weekly Reports describes an E. coli O157:H7 outbreak associated with a petting zoo. The outbreak, which occurred at a day camp in Florida in 2007, involved 7 infected individuals. Two children were hospitalized. The same E. coli strain affecting the people was found in the
Possible E. coli O157 infections from dogs
Escherichia coli (E. coli) O157 is a particularly important bacterium that can cause very serious disease in people, including diarrhea and a severe kidney disorder called hemolytic uremic syndrome (HUS). Infection in people typically results from ingesting the bacterium from contaminated food products. The main reservoir of E. coli O157 is in
E. coli O157 outbreak tentatively linked to livestock show
An outbreak of E. coli O157 – the particularly nasty strain of E. coli that can cause hemolytic uremia (a serious kidney disease) and death – has been identified in Colorado, and signs are pointing toward a livestock show as the source. So far, 20 people have been identified as infected, including 19 children.
Sharing E. coli with your dog
A recent study, published in the American Journal of Veterinary Research, investigated the relationship of E. coli bacteria in people and their pets. This study reported a number of interesting findings:
- When they compared the molecular fingerprints of E. coli from people and pets, they were the same 10% of the time. This means
Raw meat feeding revisited: what are the risks and benefits of raw diets for dogs?
Feeding raw meat diets to dogs is a very controversial issue. Some proponents passionately advocate these diets (e.g. the BARF diet) based on vague and unproven recommendations. Opponents cite various studies showing that pets fed raw meat (not surprisingly) have high carriage rates of potentially harmful bacteria such as Salmonella, and reports of
Coroner blames cat in owner’s death from E. coli
The inquest was told that there were three main possible sources of E. coli: food, travel and animals. The coroner determined that the owner most likely acquired E. coli from handling the cat or cleaning its litter box.
There is no indication why this conclusion was reached, and it seems to be a rather
E. coli and dogs
Summer is prime season for E. coli infections in people, which are often associated with eating undercooked hamburgers, and less often with contact with animals at events like petting zoos. Escherichia coli is a bacterium that is very commonly found in most animals, including a large percentage of healthy individuals. Some E. coli strains
